Two bodyguards for hip-hop superstar Ja Rule are suspected of gunning down a pair of men – one fatally – after a party for the rapper at a Midtown nightclub, The Post has learned.

The shooting may have been revenge for the robbery of a brother of Ja Rule’s bosomy buddy, racy rapper Foxy Brown, law-enforcement sources said.

Security-camera tape seized by the NYPD after the shooting at 3:45 a.m. on Dec. 27 showed part of the action when Ja Rule and his entourage emerged from the LQ nightclub, and two of his protectors peeled off and allegedly opened fire.

When the smoke cleared, two ex-cons connected to the hip-hop world were hit.

Moore is the older brother of Tyran “Ta-Ta” Moore, who has been linked to the massive federal murder and drug probe surrounding the record label formerly known as Murder Inc., which launched the careers of Ja Rule and Ashanti.

They also want to quiz the megastar rapper, his chauffeur and a young woman who was with him at the time of the slaying.

“We think Ja Rule had to know what his people were about to do,” one law-enforcement source said.

Both victims were well known in the tight-knit universe of rappers from Queens that includes Ja Rule, who was born Jeffrey Atkins and reared in Hollis.

Sources said rumors persisted in rap circles that Clark and Moore had ripped off one of Foxy Brown’s two brothers in an incident that was never reported to police.

Clark spent 12 years in jail for weapons possession, and was freed last August.

Moore, who did two stints in prison for weapons possession and assault, was more widely recognized because of his brother, Tyran. Tyran is an ex-lover of Sandra “Pepa” Denton from the groundbreaking female rap group Salt’N’Pepa and a longtime associate of drug kingpin Kenneth “Supreme” McGriff, whose cash allegedly started Murder Inc.
